RustDesk iOS -> Android - No audio in Chrome browser app

[plia7]

Bug Description

When I connect to an Android target using RustDesk iOS app, go to Chrome browser, open a website with some audio playback and click play - I can't hear the audio.

How to Reproduce

1. Connect to an Android target using RustDesk iOS app.

2. Open Chrome browser app (version Chrome 94.0.4606.85).

3. Open a website with audio playback such as:
   https://www2.iis.fraunhofer.de/AAC/multichannel.html

4. Click play.

Expected Behavior

Audio should be heard just like audio is heard in other audio based apps such as Youtube app, games apps, etc.

Operating system(s) on local side and remote side

iOS 14.4.1 -> Android 11; moto g pure Build/RRHS31.Q3-46-123-5-4

RustDesk Version(s) on local side and remote side

1.1.10 -> 1.1.10-1

Additional Context

• My Android Chrome app is configured to allow sound to all sites (Chrome Settings -> Site settings -> Sound: Allowed).

• Other audio based apps such as Youtube and games apps audio is heard through RustDesk iOS so it's only an issue with Chrome browser app.

• If I use a different app to connect to the same Android target such as Scrcpy 2.0+, I can hear the Chrome browser app audio sound, so it's only an issue with RustDesk iOS.
